Synthesis and crystal structure of [Sr(urea)(NO₃)₂] _<i>n</i>.

ABSTRACT: The crystal structure of poly[di-μ₂-nitrato-μ₂-urea-strontium(II)], [Sr(NO₃)₂(CH₄N₂O)] _n , was determined using single-crystal X-ray diffraction. Crystallizing in the ortho-rhom-bic space group Aba2, the asymmetric unit consists of an Sr^II cation, two nitrate anions, and two half urea mol-ecules. The Sr^II cation adopts a distorted deca-hedral geometry coordinated by ten oxygen atoms, with Sr-O bond lengths ranging from 2.573 (3) to 2.847 (5) Å. The nitrate anions act as bidentate ligands, displaying both terminal and bridging coordination modes. The structure features a robust coordination network supported by hydrogen bonding. These results provide insight into the coord-inatio
